UNIVERSITY PARK, Pa. -- Trey Burke's been superhuman for almost the entire 2012-13 season.

On Wednesday night at Penn State, Burke dropped in 18 points and handed out six assists -- but he didn't exactly feel like Superman afterward.

Michigan's sophomore point guard committed a season-high six turnovers in a shocking 84-78 loss to Penn State that left him completely at a loss about where to go from here.

"Every time I gave the ball up they were face-guarding me," Burke said after the loss. "They were pretty much denying me. Coach just said 'have the team play 4 on 4,' then have the team play in transition and get me involved when I bring the ball up and stuff like that.

"I think it worked to a certain extent, but it kind of slowed our offense down because a lot of times I'm the guy coming off the pick and roll. But they just, I don't know, man, they had a good scheme and they played hard."

Burke's frustration didn't just stop with his team's offensive or defensive effort, either.

He wasn't exactly thrilled with the way the game was called. Penn State got to the foul line 17 times in the final 10 minutes, as Michigan was whistled for 10 fouls during that stretch.

Burke wasn't asked about the officiating, but he did offer his opinion anyway.

"I don't usually say much to the media about refereeing, but we didn't get a lot of calls tonight," Burke said. "That's not an excuse, we should've played harder in the last five minutes, but it was tough to guard, it was tough to even block a shot. Every time they got into the paint, they called a foul.

"Like I said, I'm not making an excuse as to why we lost, but we tried to play aggressive defense and sometimes we didn't get the calls we felt we should get."

Asked directly about the officiating after the game, Michigan coach John Beilein declined to give a comment.

Penn State coach Patrick Chambers admitted afterward that he had his team completely key on stopping Burke, hoping it would then cut the heart out of the rest of the Michigan offense.

Mission accomplished.

Burke went 5 of 10 from the floor, 1 of 4 from behind the 3-point line and 7 of 8 from the foul line. But when crunch time came, he went away -- and the rest of the offense went with him.

Michigan didn't get a single field goal during the final 6:30 of regulation, and Burke's last made attempt from the floor was a jumper with 7:29 to play.

"I threw everything and the kitchen sink at (Burke)," Penn State coach Patrick Chambers said afterward. "You name it, I did it."

Beilein credited Penn State for flustering Burke, but had no other real answers for why the Wolverines couldn't get a basket during the final stretch.

At some point, he said, it was just a matter of will.

"We had some good shots, but not enough good ones," Beilein said. "They took advantage of some situations where we did not play with the type of fortitude that you need."
